I recently took a shot of the Milky Way in Australia. I only had the Oly 9-18mm with me, which I know is not the best lens to shoot this scene. Still, the Milky Way is at least visible. But I am struggling to get a decent picture in post. I open the raw file in Darktable, and I see a lot of red and blue and other coloured stars. Is that noise? Also struggling to find the right white balance setting, so the colours and nebula in the Milky Way become visible. I checked some tutorials, but that didn't really get my anywhere. I uploaded the raw file; if anybody has the time to take a quick look and give me some advice on how to make a nice picture out of this, I would be very grateful!
